SPECIFICATION forming part of Letters PatentNo. 521,755, dated June 19, 1894.

Application filed October 20, 1893- Serial No. 488,745. (No model.) I

To all whom it may concern-.-

Be it known that I, PHILLIP BIRCH, a citizen of the United States of America, residing at Denver, in the county of Arapahoe and State of Colorado, have invented certain new and useful Improvements in a Combined Knife- Sharpener and Hone-Stone Holder; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked phereomwhich form a part of this specificalon.

knife Sharpeners, and consists of the features hereinafter described and claimed all of which will be fully understood by reference to the accompanying drawings in which is illustrated an embodiment thereof.

In the drawings, Figure 1 is an elevation Fig. 2 is a longitudinal section taken through the hone-stone, one of the head plates holding the sharpening devices being removed. Fig. 3 is an edge view of the device. Figs. 4 and 5 are sections taken on the and 00-00, respectively, Fig. 2. Similar reference characters indicating corresponding parts or elements of the mechanism in the views, let the numeral 5 designate the two head plates, recessed to receive the elliptical plates 6 which constitute the Sharpeners. The parts 6 are preferably so located that their greatest diameters are approximately parallel; their edges are beveled and touch each other at a point about midway between their extremities. The head plates are centrally slotted to expose the adjacent edges of the sharpening plates and to permit the introduction of the instrument to be sharpened as far as the meeting edges of plates 6. The plates 5 are further recessed My invention relates to improvements in to receive the extremities 7 of a handle 7 composed of some suitable wire Whose extremities are bent outward so that when the head plates are fastened together, these extremities cannot be withdrawnor detached. From the extremities 7 the handle is shaped suitably to embrace a hone-stone 8 whose parallel sides are grooved to receive the same. One extremity of the hone-stone engages the head plates, while at the opposite extremity, the wire 7 is bent inward, whereby the stone is locked in place. From the parts 7 c the Wire is fashioned into a suitable hand piece 7 The head plates5 are secured together by small screws or in any other suitable manner.

Instead of the hone-stone, an emery or other platehaving a suitable sharpening surface, may be employed.

In using myimproved instrument, the knife to be sharpened is inserted between the adjacent edges of the sharpening plates 6 and drawn back and forth a few times or until the desired result is attained, after which the edge of the knife may be smoothed or further sharpened upon the hone-stone or emery plate to any extent desired.

' Having thus described my invention, what I claim is As an improved article of manufacture, the herein described knife sharpener, consisting of the head plates, sharpener plates held between the recessed head plates, the latter being slotted to expose the adjacent edge of the sharpener plates, a wire handle connected to the head plates, and a hone stone seated between and retained by the sides of the wire handle, substantially as described. 7

In testimony whereof I afiix my signature in the presence of two witnesses.
